Abstract

L'invention concerne un procédé servant à une transmission de données série dans un système de bus ayant au moins deux participants au bus qui échangent des trames de données par l'intermédiaire du bus. Les participants au bus décident en fonction d'un identifiant les trames de données qu'ils reçoivent, lesdites trames de données comportant une structure logique selon la norme CAN ISO 11898-1. La longueur de bits temporelle (L1, L2) à l'intérieur d'une trame de données peut recevoir au moins deux valeurs différentes. Pour au moins une première plage prédéfinie ou pouvant être prédéfinie à l'intérieur de la trame de données, la longueur de bits temporelle (L1) correspond aux spécifications de la norme CAN ISO 11898-1, dans au moins une deuxième plage prédéfinie ou pouvant être prédéfinie la longueur temporelle de bits (L2) est réduite par rapport à la première plage, et une commutation de la longueur de bits temporelle est signalée par l'émetteur par un marquage (310) contenu dans la même trame de données ou dans une des trames de données précédentes.
